Duplicate statements sent and LRS not connected on language changes

[kevindoherty30]

Subject of the issue

Duplicate xAPI statements are sent when a user changes language and LRS not connected message is triggered

Your environment

• Framework 5.40.10 (and earlier)
• All browsers
• All devices/OS
• xAPI v1.1.8 (and earlier)
• Language Picker v5.5.3

Steps to reproduce

Create a multi-language course with any components but a simple test is to create a single page with a text component and accordion component on the languages
Add xAPI extension
Download
Test on platform with LRS connected
Select language from lang picker screen
Click on switch language icon
choose another language
view the page, view the text component and complete accordion component

Expected behaviour

We should receive one completed statement for the text component and one completed statement for the accordion component

Actual behaviour

We receive two statements for each component, ms apart

###Additional information:
If you switch languages again, an LRS not connected message appears, but if you then complete the components you will see new statements sent to the LRS - but instead of 2 per component it now increases to 4 per component.
The more you switch the more duplicate statements get generated, and the more times the LRS not connected message is generated when the language is switched - you need to click multiple times to dismiss
